Fake flash drive
This is the most (or one of the most) well-known fake flash drive images. Looking at it once again, I suddenly spotted that it is actually not a pen drive. It is, or rather it is supposed to be, a DLink DWL-G122 USB Wireless Network device.
Following is the more realistic, and more widespread variant of the fake pen drive.
This one is working, but just mislabelled. Typically, they get the 2GB pen drive, stick a 32GB label onto it, and then resell at higher prices. The following image is a lesser size older model pen drive forced into the smaller case of the newer model:
Note that the PCB is cut off a little bit at the top to make it fit and then glued to the case with a blob of a silicone sealant.
The flash drive relabelled from 2GB to 32GB still only has 2GB of actual capacity. So if there is more data written to the flash drive, the excess data has to go somewhere. There are two possibilities: the excess data either goes nowhere, it is just discarded and never stored at all, or the data is written again from the beginning of the device, thus overwriting what was there previously. Either way, it is not possible for a data recovery software to retrieve the data in excess of 2GB capacity.
